6 Insane Things Science Can Predict About You at Infancy

#3. Smaller Babies Do Worse on Exams

Want to know whether it's worth it to put money aside for your baby's college education? Just put that baby on a bathroom scale.* A study conducted in England found that the smaller the baby at birth, the poorer he or she performs on exams later in life.

The researchers picked out 334 kids from schools that had a pretty homogenous socioeconomic enrollment set (so they could prevent winding up with a bunch of kids who were both small and stupid for some extraneous reason, like, say, they were malnourished due to their parents' crippling meth addiction).

Half of the kids selected were of lower-than-normal birth weight, and the others were normal or larger. At 8 years old, the kids were all given IQ tests. The researchers then examined all of their GCSE (a standardized test) scores when the kids had turned 20. The normal birth weight group not only scored higher on the IQ tests, but also scored an average of a half grade better on their GCSE tests than their less wind resistant classmates. They also completed more of the exam (the GCSE lets you choose which portions you take).

The leader of the research team, Professor Peter Pharoah of the University of Liverpool, stresses that this doesn't mean that your gigantic freak mammoth baby is going to win a Nobel Prize. But nevertheless, science doesn't quite know how it works, though it does seem to contradict the cliche of the short, scrawny nerd outsmarting his ogrish jock classmates.

#2. Moody Toddlers Grow Up to Be Gamblers

Back in the '70s, some researchers in Dunedin, New Zealand, decided to examine a bunch of 3-year-olds to see whether they could predict future temperaments in kids who are still only old enough to drool on themselves and regard mundane objects with confused fascination. Observing the toddlers during independent 90-minute sessions, the researchers classified the kids as best they could as well-adjusted, reserved, confident, inhibited or "undercontrolled" (because you can't call toddlers "assholes").

GettyWhich might be part of the reason so many of them are assholes.

Roughly 10 percent of the children were in that last category, which involved "lack of self-control, rapidly shifting emotions, impulsive and willful behavior and relatively high levels of negative feelings."

When they returned to study those kids at ages 21 and 32, the researchers discovered an unexpected side effect of their subjects' infant dickishness -- they didn't all wind up in jail, as might be expected, but scientists did find that when the "undercontrolled" kids grew up, they were twice as likely to have gambling problems as any other temperament classification.

Lead researcher Wendy Slutske cautions that just because your toddler is a mood-shifting jerk, that doesn't mean he or she is destined to be a compulsive gambler, but she suspects that some are born vulnerable to addiction. This would explain why some people can hit up a penny slot, win $100 and never gamble ever again, and others play until they're buried in the desert.

Raine got his hands on a mental illness study from the 1970s that tested the fear responses of about 1,800 3-year-olds. The toddlers were exposed to two sets of sounds -- one was a neutral tone that was followed by nothing, and the other was a neutral tone followed by a shit-your-pants-terrifying wail. The toddlers quickly figured out when to expect the scary noise, and most of them sweated in response -- a normal fear reaction. Then again, there were some kids who showed no signs of fear at all.

In 2009, Raine checked in to see what the original test subjects had been doing with their lives, and found something fascinating. Along with everyone being a little fatter and uglier than they were when they were 3, Raine found that 137 of the test subjects had criminal records -- and not one of them had been among the group who had sweated during the fear study when they were 3.

The discovery was examined for any result-skewing factors such as race, gender and income, but more than anything else, the outstanding variable was that all of the convicted subjects had been fearless toddlers. This leaves us with an unsettling implication -- the possibility that some people are actually born criminals.

Getty"Rise and shine, you pukes. You got 30 minutes in the rec room, let's move."

Before you use this research to establish a Minority Report-style pre-emptive justice system, Raine notes that many other kids who also didn't show fear as babies went on to lead perfectly law-abiding lives. We would like to note that this only proves that they were never caught committing any crimes. Or maybe they grew up to be scientists who tormented 3-year-olds by blasting scary noises at them.
